Nicotine is a fast-acting poison in pets, and the products that carry it have multiplied: cigarettes and butts, vape liquid, pouches, patches and nicotine gum. E-liquid deserves special mention, because it is the most concentrated form most households now contain.
How much is safe?
There is no safe amount, and the concentration varies hugely by product. A discarded butt still holds a meaningful quantity of nicotine, and dogs will eat them from ashtrays and gutters. Vape refill liquid is far worse per millilitre and is often flavoured to be sweet. Nicotine gum stacks two problems, because it frequently also contains xylitol. Patches, including used ones, hold a substantial residual dose.
What happens if a cat eats too much?
Nicotine moves quickly — signs usually begin within 15 to 60 minutes. The first phase is stimulation: drooling, vomiting, agitation, tremors, a racing heart and rapid breathing. That can be followed by a depressive phase with weakness, collapse, a slow heart rate, difficulty breathing and seizures. The speed is what makes this dangerous; there is not a long window in which to decide whether to act.
⚠ What to do if your cat ate cigarettes & tobacco
Call and go in without waiting (ASPCA 888-426-4435 · Pet Poison Helpline 855-764-7661). Say exactly what the product was — butts, e-liquid with its strength in mg/ml, gum, or a patch — because the dose calculations are entirely different. If it was nicotine gum, mention xylitol as a second hazard. Do not induce vomiting at home; nicotine can cause seizures and a vomiting animal that is convulsing may inhale. Most pets do well with rapid decontamination and supportive care.

Frequently asked questions
My dog ate a cigarette butt from the street — is that enough to matter?
Potentially yes, especially for a small dog. Butts retain nicotine and are one of the more common exposures. Call with your dog's weight and how many were eaten.
How dangerous is vape liquid compared with cigarettes?
Considerably more, because it is concentrated and swallowed as a liquid, so absorption is fast. A chewed refill bottle is an emergency.
